HUO ZHE VS HAI SHI

I need to know when to use huo zhe or hai shi. I can't find it in any of the notes. HELP. I have an exam on this on Monday and I am confused!

你好kathie, 还是 is only used in questions such as "do you want coffee or tea?" 或者 is used to mean no in statements such as "I think I will go to Beijing or Qingdao" I hope this helps you and good luck for your exam! - Lin

But there isn't a "no" in a statement such as "I think I will go to Beijing or Qingdao"!

huozhe is better translated as "perhaps" - e.g. I will go to Beijing, or perhaps Qingdao. e.g. Ta-mingtian huozhe-'bu-neng-qu. - Perhaps he won't go tomorrow.

Thanks for the answers all - But I am even more confused now.

您 好 嗎？ I'm quoting now from "A Guide to Proper Usage of Spoken Chinese", 2nd ed. by Tian Shou-he, The Chinese University Press, Hong Kong ISBN 962-201-539-5 "Although haishi and huozhe both mean "or", the distinction between them is a clear one. Haishi can be used as a question word whereas huozhe cannot. When haishi is not used as a question word, it is equivalent to huozhe." There're quite a few examples listed in the book showing the differences. If you can't locate a copy of the book perhaps Lin Ping could arrange something for faxing.

大家好！ Thank you Javier for that explanation. Sorry if my English wasn't that clear. Remember kathie that 或者 huozhe and 还是 haishi in most cases both mean "or". However, 还是 is only used in a question and 或者 is used in statements. Are you still confused? I hope this helps! - Lin Ping
